On this special day, with my dear family and friends nearby, I am thankful for all that I have received and for all that we are able to share with each other. But it is outside, in nature and in wildness, away from wrapping paper and instruction booklets, that I am humbled by what I have been given. Nature is free and it is mine, and today my family and I will step outside and bask in its sharing, for at least a few minutes.

Yes, it is.
Merry Christmas to all of you, your families … and the flowers.

I have a citrus with iron deficiency. Give it some iron — right? I've added iron before with little effect. Should I use a liquid iron, powdered iron, granulated iron or what?

Iron deficiency in citrus is a rather common sight. There are a couple of things you should know about applying iron. First, iron will not be absorbed well by the roots of the plant when the soil is cool. This is especially true in a sub-tropical plant like a citrus, which is essentially dormant during the winter months. In addition, iron is absorbed poorly by plants when the soil is somewhat alkaline (high pH).
My suggestion is to use an iron that has been chelated; either liquid or granular is fine. Chelating of the iron helps it to be absorbed more easily by the plant and it also helps the iron persist in the soil a bit longer. However, wait until about March to begin applying the iron and simultaneously add a thick organic and acidic mulch over the soil at the base of the plant, but not in contact with the trunk.
